Gortnaclea Castle, County Laois is a 16th century tower house originally built by the Mac Giolla Phádraig family on a site overlooking the Gully river. It is famous for having been the place where in April 1600 Thomas Butler, 10th Earl of Ormond, a long-time ally of the English crown but by then aged almost 70, was held hostage by Owny MacRory O’More. At the end of the month, O’More sent his demands to the government, which included the removal of all English garrisons from that part of the country. This stipulation – and sundry others – were not met but the earl, by then in poor health, was eventually released after the payment of £3,000 (and lived for another 16 years). Of five storeys, Gortnaclea is a typical tower house of the period but unfortunately its easterly entrance front has long since collapsed, bringing down the spiral staircase which would have been immediately inside the main door; the graceful curving wall of the staircase can be seen on the north-east corner.
